Braided streams,such as the Brahmaputra River,are found in areas
A)where the load is lower than the capacity.
B)where the bed and suspended loads are low.
C)that are subject to new sediment from glaciers or landslides.
D)subject to sediment erosion from the river bed.
E)with solid rock or resistant channel walls.

Question

Quizplus · Accepted Answer

Braided streams form in areas where there is excess sediment supply from sources such as glaciers or landslides. As a result, the sediment load is higher than the capacity of the river to transport the sediment, causing it to form multiple channels that braid and interweave with each other. Choice A and B suggest that the load or capacity is low, which is incorrect. Choice D is also incorrect, as sediment erosion would decrease the sediment load and reduce the braiding. Finally, choice E suggests that the stream has solid rock or resistant channel walls, which is not conducive to braiding.
